The floorhead provided with the S5280 MedicAir vacuum cleaner now features the Allergotec hygiene sensor, a device which automatically detects particulate contamination levels. The heart and soul of the hygiene is a small metal sensor plate located above the floorhead at the connection to the suction tube. Allergens, which adhere to household dust particles, impact this plate on their passage through the air duct, releasing tiny electrical impulses. As well as ensuring superb levels of hygiene, the Miele Active HEPA filter also guarantees odour-free room air, thanks to its layer of activated charcoal. Electronic suction control allows the vacuum cleaner to adapt with ease to different floor coverings. The Allergotec floorhead adapts to both carpeting and smooth floors by operating a footswitch and can be changed from the one to the other. 4.5 Litres Dust capacity Bagged Dust collection Dusting nozzle Active HEPA Filter type Floor head with hygene sensor Hard floor tool 1.75 m Hose length Mattress nozzle Metal tubes 5 filtration levels 2200 Watts Power Surface adjuster Upholstery tool Variable power.
